Describe the bug

In Metapath, if one uses an explicit qualified name for a field, flag, or assembly, a compilation exception occurs (MPST0003).

Who is the bug affecting

Developers of Metaschema-enabled tooling and engineers who write Metapath with explicit use of qualified names for querying specific data elements in Metaschema-bound document instances by their namespace explicitly.

How do we replicate this issue

  1. Write a Metapath-based constraint with a @target with a qualified name, such as
  2. Use the metaschema-java library or CLI to validate the constraint.
  3. Locate one or more of the following exceptions.

NOTE: The full example code can be found in the repro branch below.

Expected behavior (i.e. solution)

The QName is honored and the path successfully evaluates on the explicitly identified QName.
